The 5E Electric Smoker from Superior Signal offers a cost-effec­tive solution to find difficult leaks and odors in residential and com­mercial plumbing systems. Con­nect the blower to any plumbing clean-out or vent or to the septic tank, and use an appropriately sized smoke candle to force smoke through faults and cracks to identify the sources of odor and hard-to-find leaks. It handles all resi­dential and commercial smoke testing applications using smoke candles from 30 seconds to three minutes. Smoke tests take just minutes to perform and see immediate results. The unit comes with an 8-foot industrial-grade flex-hose, weighs just 8 pounds, and requires no maintenance. 800/945-8378; www.superiorsignal.com.
